Abstract

Cette invention concerne un système en porte-à-faux pour un appareil de forage comprenant une coque, une poutre accouplée à la coque, un élément d'extension accouplé à la poutre et un élément de retenue espacé d'un élément de support et accouplé à l'élément d'extension. Une première extrémité de la poutre peut être étendue au-dessus d'un bord de la coque tandis qu'une seconde extrémité de la poutre est disposée sur la coque. L'élément d'extension accroît la portée longitudinale de la poutre. L'élément de support est disposé de manière adjacente au bord de la coque. L'élément de retenue est conçu pour appliquer une force sur l'élément d'extension dans le sens de la coque quand la première extrémité de la poutre est étendue au-dessus du bord de ladite coque. L'invention concerne en outre un procédé permettant d'accroître la capacité du système en porte-à-faux, ledit procédé comprenant l'étape consistant à augmenter l'espacement entre l'élément de support et l'élément de retenue.
